HEC (Hydroxyethylcellulose) is a water-soluble polymer compound modified from natural cellulose. It is widely used in cosmetic formulas, mainly as a thickener, stabilizer and emulsifier to enhance the product’s feel and effect. As a non-ionic polymer, HEC is particularly functional in cosmetics.
1. Basic properties of HEC
HEC is a modified cellulose derivative generated by reacting natural cellulose with ethoxylation. It is a colorless, odorless, white powder with good water solubility and stability. Due to the large number of hydroxyethyl groups in its molecular structure, HEC has excellent hydrophilicity and can form hydrogen bonds with water molecules to improve the texture and feel of the formula.
2. Thickening effect
One of the most common uses of AnxinCel®HEC is as a thickener. Due to its macromolecular structure, HEC can form a colloidal structure in water and increase the viscosity of the solution. In cosmetic formulas, HEC is often used to adjust the consistency of products such as lotions, gels, creams and cleansers, making them easier to apply and absorb.
Adding HEC to lotions and creams can make the texture of the products smoother and fuller, and it is not easy to flow when used, which improves the consumer experience. For cleaning products, such as facial cleansers and shampoos, the thickening effect of HEC can make the foam richer and more delicate, and increase the durability and effectiveness of the product.
3. Improve rheological properties
Another important role of HEC in cosmetics is to improve rheological properties. Rheological properties refer to the deformation and flow properties of a substance under the action of external forces. For cosmetics, good rheological properties can ensure the stability and ease of use of the product in different environments. HEC adjusts the fluidity and adhesion of the formula by interacting with water molecules and other formula ingredients. For example, after HEC is added to the emulsion, the fluidity of the emulsion can be adjusted so that it is neither too thin nor too viscous, ensuring proper spreadability and absorbency.
4. Emulsion stability
HEC is also commonly used in emulsion and gel cosmetics as an emulsifier stabilizer. Emulsion is a system composed of water phase and oil phase. The role of emulsifier is to mix and stabilize the two incompatible components of water and oil. HEC, as a high molecular weight substance, can enhance the structural stability of the emulsion by forming a network structure and prevent water and oil separation. Its thickening effect helps to stabilize the emulsification system, so that the product will not stratify during storage and use, and maintain a uniform texture and effect.
HEC can also work synergistically with other emulsifiers in the formula to improve the stability and moisturizing effect of the emulsion.
5. Moisturizing effect
The moisturizing effect of HEC in cosmetics is another important function. The hydroxyl groups contained in the HEC molecule can form hydrogen bonds with water molecules, help absorb and lock in moisture, and thus play a moisturizing role. This makes HEC an ideal moisturizing ingredient, especially in dry seasons or in care products for dry skin, which can effectively maintain the moisture balance of the skin.
HEC is often added to skin care products such as creams, lotions, and essences to improve the moisturizing and softness of the skin. In addition, AnxinCel®HEC can also help the skin form a protective film, reduce water loss, and improve the skin’s barrier function.
6. Skin friendliness and safety
HEC is a mild ingredient that is generally considered non-irritating to the skin and has good biocompatibility. It does not cause skin allergies or other side effects and is suitable for all skin types, especially sensitive skin. Therefore, HEC is often used in baby care, sensitive skin care, and other cosmetics that require a mild formula.
7. Other application effects
HEC can also be used as a suspending agent in cleansers to help suspend particulate matter such as scrub particles and plant essences so that they are evenly distributed in the product. In addition, HEC is also used in sunscreens to provide a light coating and enhance the sunscreen effect.
In anti-aging and antioxidant products, the hydrophilicity of HEC also helps to attract and lock in moisture, helping active ingredients to better penetrate the skin and enhance the effectiveness of these products.
As a cosmetic raw material, HEC has multiple effects and can play an important role in improving product texture, improving rheological properties, enhancing emulsification stability, and providing moisturizing effects. Its safety and mildness make it suitable for a variety of cosmetic formulations, especially for dry and sensitive skin. As the cosmetic industry’s demand for mild, effective, and environmentally friendly formulas increases, AnxinCel®HEC will undoubtedly continue to occupy an important position in the cosmetic field.
